DETAILED DESCRIPTION

Hereinafter, example embodiments will be described in more detail with reference to the accompanying drawings.

In various embodiments, building management platforms such as a building management system includes digital representations of physical spaces. For example, a building management system may include a digital twin of a building that represents the people, places, assets, and events within the building. In various embodiments, digital twins are generated during the construction of a building. For example, an architect may generate a building information model (BIM) that is used by builders to construct a building and service personnel to maintain the building. Additionally or alternatively, digital representations such as digital twins may be generated for existing buildings. For example, a building management system of an existing building may generate a digital representation of the building. However, it may be difficult to generate a digital representation of a building (new, existing, or otherwise). For example, manually identifying the assets in a building may be difficult and time consuming. As a further example, some sources of existing building data may not be easily translatable to a digital representation and may require manual transfer. Further, configuring the devices of the buildings/spaces to work properly with one another and with the building management system can be difficult and time-consuming as well. In general, it may be desirable to avoid manually generating digital representations of buildings (e.g., to reduce input errors, because of the amount of data to be input, etc.). Therefore, systems and methods of self-configuring and commissioning spaces are needed. Specifically, system and methods to facilitate ingesting building data, generating a digital representation, and deriving new information based on the digital representation are needed. Virtual representations, digital representations, smart entities, and digital twins are used interchangeably in the present disclosure; in other words, where the present disclosure refers to virtual representations or smart entities, it should be understood that the features discussed could be implemented using digital twins or any other digital counterpart (e.g., updated in real-time, near real-time, periodically, in response to events, or in any other fashion). Additionally, in various embodiments, the systems and methods of the present disclosure can utilize digital twins for higher-level entities (e.g., such as buildings or campuses that include or are otherwise related to particular spaces, assets such as building equipment, people, and/or events) and/or for lower-level entities, such as digital twins of particular spaces (e.g., rooms, floors, etc.), people, assets (e.g., particular pieces of building equipment or groups of building equipment), and events. All such implementations are contemplated within the scope of the present disclosure.

One solution may include a smart configuration and commissioning system. The smart configuration and commissioning system may automate the process of generating and deploying a digital representation of a building, thereby reducing or eliminating a need for manual intervention. In various embodiments, the smart configuration and commissioning system may ingest and interpret external data sources (e.g., BIM data, enterprise management data, personnel data, etc.), extract semantic information from external data sources, dynamically determine configuration information, automatically enrich digital representations with derived information, and/or generate digital representations for spaces. In some implementations, the digital representations may be used to configuration and/or control of the building equipment and/or other assets contained in the buildings/spaces, and may significantly lower the time and expense of commissioning and configuring new buildings and spaces.

Referring now to FIGS. 1A-1B, a block diagram of a smart building environment 100 is shown, according to an exemplary embodiment. Smart building environment 100 is shown to include cloud building management platform 140. Cloud building management platform 140 may be configured to collect information from a variety of different data sources. Cloud management platform 140 may create digital representations, referred to as “digital twins,” of physical spaces, equipment, people, and/or events based on the collected information. In various embodiments, the digital representations are stored in an entity graph. In brief overview, an entity graph is a data structure representing entities (e.g., spaces, equipment, people, events, etc.) and relationships between the entities. In various embodiments, the entity graph data structure facilitates advanced artificial intelligence and machine learning associated with the entities. In various embodiments, entities within the entity graph data structure include or are associated with “agents,” or software entities configured to take actions with respect to the digital twins/real world entities with which they are associated. In some implementations, the agents may be configured to implement artificial intelligence/machine learning methodologies. The agents may be configured to facilitate communication and collection of information between the variety of different data sources. Each of the data sources may be implemented as, include, or otherwise use respective agents for facilitating communication amongst or between the data sources and cloud building management platform 140.

In various embodiments, cloud building management platform 140 collects data from buildings 10. For example, cloud building management platform 140 may collect data from buildings 10 such as a school, a hospital, a factory, an office building, and/or the like. It should be understood that the present disclosure is not limited to the number or types of buildings 10 shown in FIG. 1B. As new devices/components/spaces/buildings/events/control loops are added or otherwise incorporated into smart building environment 100, new digital representations (and associated agents, etc.) may be dynamically generated and incorporated into the entity graph data structure.

Buildings 10 may include entities 12. Entities 12 may include spaces, equipment, people, and/or events. In some embodiments, entities 12 include spaces such as floors, rooms, zones, campuses, buildings, and the like.

In some embodiments, entities 12 include equipment such as inventory, assets, furniture, vehicles, building components, devices, and the like. For example, entities 12 may include devices such as internet of things (IoT) devices. IoT devices may include any of a variety of physical devices, sensors, actuators, electronics, vehicles, home appliances, and/or other items capable of communicating data over an electronic network (e.g., smart lights, smart appliances, smart home hub devices, etc.). In some embodiments, entities 12 include events such as meetings, fault indications, alarms, and the like. In various embodiments, cloud building management platform 140 receives information associated with buildings 10 and/or entities 12 and generates entity graph 170 based on the received information.

Entity graph 170 is described in greater detail below with reference to FIG. 2A-2B.

Smart building environment 100 may include building management system (BMS) 102. In various embodiments, BMS 102 communicates with cloud building management platform 140 to facilitate management and control of buildings 10 and/or the various operations described herein. BMS 102 may be configured to control, monitor, and/or manage equipment in or around a building or building area (e.g., such as buildings 10, etc.). For example, BMS 102 may include a HVAC system, a security system, a lighting system, a fire alerting system, and any other system that is capable of managing building functions or devices, or any combination thereof. Further, each of the systems may include sensors and other devices (e.g., IoT devices) for the proper operation, maintenance, monitoring, and the like of the respective systems. In some embodiments, each of buildings 10 is associated with a BMS 102. Additionally or alternatively, a single BMS 102 may manage multiple buildings 10. For example, a first BMS 102 may manage a first building 10, a second BMS 102 may manage a second building 10, and a third BMS 102 may manage the first and second buildings 10 (e.g., via the first and second BMS 102, in a master-slave configuration, etc.), as well as a third building 10. In various embodiments, BMS 102 communicates with building subsystems 120.

In various embodiments, building subsystems 120 include fewer, additional, or alternative subsystems. For example, building subsystems 120 may additionally or alternatively include a refrigeration subsystem, an advertising or signage subsystem, a cooking subsystem, a vending subsystem, a printer or copy service subsystem, or any other type of building subsystem that uses controllable equipment and/or sensors to monitor or control a building 10. In some embodiment each of buildings 10 includes building subsystems 120. Additionally or alternatively, multiple buildings 10 may share at least some of building subsystems 120.

Each of building subsystems 120 may include any number of devices (e.g., IoT devices), sensors, controllers, and connections to facilitate functions and control activities. For example, HVAC subsystem 132 may include a chiller, a boiler, any number of air handling units, economizers, field controllers, supervisory controllers, actuators, temperature sensors, and other devices for controlling the temperature, humidity, airflow, or other variable conditions within buildings 10.

In various embodiments, communications via communications interface 104 is direct (e.g., local wired or wireless communications). Additionally or alternatively, communications via communications interface 104 may be via network 20 (e.g., a WAN, the Internet, a cellular network, etc.). For example, cloud building management platform 140 may communicate with BMS 102 using a wired connection and may communicate with client devices 40 (e.g., via BMS 102, etc.) using a cellular connection (e.g., a 4G or 5G access point/small cell base station, etc.). As a further example, communications interface 104 may include an Ethernet card and port for sending and receiving data via an Ethernet-based communications link or network.

According to some embodiments, memory 146 is communicably connected to processor 144 via processing circuit 142 and includes computer code for executing (e.g., by processing circuit 142 and/or processor 144) one or more of the operations described herein.

Memory 146 may include data management circuit 148, entity graph circuit 150, analytics circuit 152, event management circuit 154, applications circuit 156, and/or user interface circuit 158. Data management circuit 148 may be configured to collect, manage, and/or retrieve data. In various embodiments, data management circuit 148 receives data samples from buildings 10 (e.g., via BMS 102, directly, etc.) and stores the data samples in structured storage. For example, the data samples may include data values for various data points. The data values may be measured and/or calculated values, depending on the type of data point. For example, a data point received from a temperature sensor may include a measured data value indicating a temperature measured by the temperature sensor. Data management circuit 148 may receive data samples from systems, components, and/or devices (e.g., IoT devices, sensors, etc.) within smart building environment 100 (e.g., remote systems and applications 30, client devices 40, third party services 50, BMS 102, building subsystems 120, etc.) and/or from external systems (e.g., the Internet, etc.). For example, data management circuit 148 may receive timeseries data from an occupancy sensor associated with one of buildings 10 and facilitate storage of the timeseries data in structured storage (e.g., in entity graph 170, etc.). As a further example, data management circuit 148 may receive an electronic calendar event (e.g., a meeting invitation, etc.) from one of client devices 40 and facilitate storage of the electronic calendar event in structure storage (e.g., in entity graph 170, etc.).

Referring now to FIGS. 2A-2B, an entity graph 200 is shown in greater detail, according to an exemplary embodiment. In brief overview, entity graphs such as entity graph 170 and/or entity graph 200 are structured data stored in memory (e.g., a database, memory 146, etc.). Entity graphs such as entity graph 200 and/or entity graph 170 may include digital twins. Digital twins may be digital representations of real world spaces, equipment, people, and/or events. In various embodiments, digital twins represent buildings, building equipment, people associated with buildings, and/or events associated with buildings (e.g., buildings 10, etc.). An entity graph may include nodes and edges, where each node of the entity graph represents an entity and each edge is directed (e.g., from a first node to a second node) and represents a relationship between entities (e.g., indicates that the entity represented by the first node has a particular relationship with the entity represented by the second node). For example, an entity graph may be used to represent a digital twin of a person.

Entities can be things and/or concepts related to spaces, people, and/or asset. For example, the entities could be “B7F4 North”, “Air Handling Unit,” and/or “meeting room.” The nodes can represent nouns while the edges can represent verbs. For example, the edges can be “isA,” “hasPart,” and/or “feeds.” In various embodiments, the edges represent relationships. While the nodes represent the building and its components, the edges describe how the building operates. The nodes and edges together create a digital twin of a particular building. In some embodiments, the entities include properties or attributes describing the entities (e.g., a thermostat may have a particular model number attribute). The components of the entity graph form large networks that encode semantic information for a building.

The entity graph is configured to enable flexible data modeling for advanced analytics, control, and/or artificial intelligence applications, in some embodiments. These applications may require, or benefit from information modeling including interconnected entities. Other data modeling techniques based on a table, a hierarchy, a document, and/or a relational database may not be applicable. The entity graph can be a foundational knowledge management layer to support other higher level applications, which can be, complex root cause, impact analysis, building powerful recommendation engines, product taxonomy information services, etc. Such a multilayer system, a system of system topologies, can benefit from an underlying entity graph.

The entity graph can be a data contextualization layer for all traditional and/or artificial intelligence applications. The entity graph can be configured to capture evidence that can be used to attribute the strengths of entity relationships within the entity graph, providing the applications which utilize the entity graph with context of the systems they are operating. Without context (e.g., who the user is, what the user is looking for, what the target of a user request is, e.g., find a meeting room, increase a temperature in my office) these applications may never reach their full potential. Furthermore, the entity graph provides a native data structure for constructing question and answer type systems, e.g., a chatbot, that can leverage and understand intent.

In various embodiments, the entity graph includes data from various sources. For example, the entity graph may include data associated with people, places, assets, and/or the like. In various embodiments, the data source(s) represent a heterogenous source data schema such as an open source common data model (e.g., a Brick Schema/extensions, etc.).

In various embodiments, entity graph includes digital twins and/or context information. A digital twin is a digital representation of spaces, assets, people, events, and/or anything associated with a building or operation thereof. In various embodiments, digital twins are modeled in the entity graph. In various embodiments, digital twins include an active compute process. For example, a digital twin may communicate with other digital twins to sense, predict and act. In various embodiments, digital twins are generated dynamically. For example, a digital twin corresponding to a conference room may update its status by looking at occupancy sensors or an electronic calendar (e.g., to turn its status “available” if there is no show, etc.). In various embodiments, digital twins and/or the entity graph include context information. Context information may include real-time data and a historical record of each system in the environment (e.g., campus, building, facility, space, etc.). Context information may be stored in the entity graph. In various embodiments, context information facilitates flexible data modeling for advanced analytics and AI application in scenarios that model highly interconnected entities.

The entity graph may not be a configuration database but may be a dynamic representation of a space, person, event, and the like. The entity graph can include operational data from entities which it represents, e.g., sensors, actuators, card access systems, occupancy of a particular space, thermodynamics of the space as a result of actuation, etc. The entity graph can be configured to continually, and/or periodically, ingest new data of the space and thus the entity graph can represent a near real-time status of cyber-physical entities and their inter-relationships. For this reason, artificial intelligence can be configured to introduce a virtual entity and new semantic relationships among entities, in some embodiments.

The entity graph is configured to facilitate adaptive controls, in some embodiments. The entity graph can be configured to adapt and learn over time. The entity graph can be configured to enable dynamic relationships between building information and other facility and enterprise systems to create new insights and drive new optimization capabilities for artificial intelligence systems. As relationships can be learned over time for the entity graph, the artificial intelligence systems and also learn overtime based on the entity graph. Entity graphs (e.g., space graphs, etc.) are described in greater detail with reference to U.S. patent application Ser. No. 16/260,078, filed on Jan. 28, 2019, the entire disclosure of which is incorporated by reference herein.

Entity graph 200 includes entities 202-258 (stored as nodes within entity graph 200) describing spaces, equipment, events, and people (e.g., business employees, etc.). In various embodiments, entities 202-258 are associated with or otherwise include agents (e.g., agents may be assigned to/associated with entities, etc.). Additionally or alternatively, agents may be represented as nodes in entity graph 200 (e.g., agent entities, etc.). Furthermore, relationships are shown between entities 202-258 directionally describing relationships between two of entities 202-258 (stored as edges within entity graph 200). In various embodiments, cloud building management platform 140 may traverse entity graph 200 to retrieve a description of what types of actions to take for a certain device, what the current status of a room is (e.g., occupied or unoccupied), etc.

As an example, entity graph 200 illustrates an office space called “B7F5 North” of a building. A smart TV referred to as “Smart TV 001” has a directional relationship to the space referred to as “B7F5 North.” The relationship may be an edge “hasLocation” indicating that the device (e.g., the smart TV represented by entity 224) has a location (e.g., the space represented by entity 202). Furthermore, a second edge “contains” from entity 202 to entity 224 indicates that the location (e.g., the space represented by entity 202) includes the device (e.g., the smart TV represented by entity 224). In some embodiments, entity graph circuit 150 generates the nodes of entity graph 200 from various data sources including a building automation system, a security system, a fire alarm, human resources system, and/or building information model (BIM) files (e.g., through an entity name matching process, etc.). Furthermore, semantic relationships may be extracted from the building information by entity graph circuit 150. In some embodiments, only a single relationship exists between entities. In some embodiments, nodes and edges are determined dynamically as building data that is received and ingested into entity graph 200. For example, cloud building management platform 140 is configured to identify a door lock and card reader and generate a number of nodes and edges in entity graph 200 representing the card reader controller operation of the door lock.

Smart Configuration and Commissioning System

Referring now to FIG. 3, smart configuration and commissioning system 300 is shown, according to an exemplary embodiment. Smart configuration and commissioning system 300 may automate a process of generating a digital representation of a space such as a building. In various embodiments, smart configuration and commissioning system 300 facilitates generating entity graph 170. Additionally or alternatively, smart configuration and commissioning system 300 may facilitate linking various models and/or subsystems. For example, smart configuration and commissioning system 300 may link a graph data structure to building subsystems such as mapping building spaces to an API of a lighting subsystem.

Network 340 may include computer networks such as the Internet, local, wide, metro or other area networks, intranets, satellite networks, other computer networks such as voice or data mobile phone communication networks, combinations thereof, or any other type of electronic communications network. In various embodiments, network 340 facilitates secure communication between smart configuration and commissioning system 300 and other systems. As a non-limiting example, network 340 may implement transport layer security (TLS), secure sockets layer (SSL), hypertext transfer protocol secure (HTTPS), and/or any other secure communication protocol.

External systems 350 may be an external source of data for smart configuration and commissioning system 300. For example, external systems 350 may include a human-resources (HR) database, an email directory, a security system, a DHCP server, a lighting control system, a visitor registration system, a parking management system, and/or the like. External systems 350 may include one or more storage mediums. The storage mediums may include but are not limited to magnetic storage, optical storage, flash storage, and/or RAM. External systems 350 may implement or facilitate various APIs to perform database functions (i.e., managing data stored in external systems 350). The APIs can be but are not limited to SQL, ODBC, JDBC, and/or any other data storage and manipulation API.

In various embodiments, external systems 350 include building model database 352. Building model database 352 may include building models describing one or more buildings and/or spaces. For example, building model database 352 may include a BIM model, an IFC file, a Revit model, a csv file, a COBie file, an RDF graph model, a TTL file, an SVG file, and/or the like. In various embodiments, building model database 352 includes data to be integrated into a digital representation of a building such as entity graph 170. For example, smart configuration and commissioning system 300 may receive a csv file including building assets for a building and may ingest the building assets into a digital representation of the building.

User devices 360 may be a source of data for smart configuration and commissioning system 300. User devices 360 may include smartphones, tablets, handheld devices, scanners, and/or the like. In various embodiments, user devices 360 are configured to provide information to smart configuration and commissioning system 300 to be integrated into a digital representation of a building. For example, a smartphone may capture LIDAR data for a space within a building and smart configuration and commissioning system 300 may integrate the LIDAR data into a digital representation of the building (e.g., to facilitate modeling and/or viewing an interior of the space, etc.). In some embodiments, user devices 360 provide user feedback data. For example, smart configuration and commissioning system 300 may operate a fan that has not been mapped to a space within a building and may receive feedback (e.g., user feedback via user devices 360 and/or sensor feedback indicating that a specific room suddenly became cold) and may determine that the fan serves the specific room. Smart configuration and commissioning system 300 may receive image data, location data, 3D data, sound data, light data, distance measurements, surveyor data (e.g., cartographic information, etc.), user feedback, user input, temperature data, motion data, and/or the like from user devices 360.

Deployed devices 370 may be devices deployed within a space such as a building. In various embodiments, deployed devices 370 include device associated with a building management system. For example, deployed devices 370 may include dampers, chillers, door locks, AHUs, smart lights, controllers, and/or the like. In various embodiments, deployed devices 370 include specific sensors such as temperature sensors, occupancy sensors, humidity sensors, vibration sensors, glass-break sensors, weight sensors, flow sensors, IR sensors, cameras, and/or the like. In various embodiments, smart configuration and commissioning system 300 receives information from deployed devices 370 and integrates the information into a digital representation of a space such as a building. For example, smart configuration and commissioning system 300 may receive a scan from a building management system that may attempt to identify deployed devices 370 that are controlled by the building management system and may generate digital representations for the identified deployed devices 370. Additionally or alternatively, smart configuration and commissioning system 300 may turn on a smart light that has not been mapped to a space within a building, may receive an indication from a camera that a light turned on in a specific room, may determine that the smart light is located in the specific room, and may update a digital representation of the building to map the smart light to the specific room.

Smart configuration and commissioning system 300 is shown to include processing circuit 310, entity graph database 312, and storage 314. Processing circuit 310 may include processor 316 and memory 318. Memory 318 may have instructions stored thereon that, when executed by processor 316, cause processing circuit 310 to perform the various operations described herein. The operations described herein may be implemented using software, hardware, or a combination thereof. Processor 316 may include a microprocessor, ASIC, FPGA, etc., or combinations thereof. In many embodiments, processor 316 may be a multi-core processor or an array of processors. Memory 318 may include, but is not limited to, electronic, optical, magnetic, or any other storage devices capable of providing processor 316 with program instructions. Memory 318 may include a floppy disk, CD-ROM, DVD, magnetic disk, memory chip, ROM, RAM, EEPROM, EPROM, flash memory, optical media, or any other suitable memory from which processor 316 can read instructions. The instructions may include code from any suitable computer programming language such as, but not limited to, C, C++, C#, Java, JavaScript, Perl, HTML, XML, Python and Visual Basic. While the present features are described as being implemented using a processor and memory, it should be understood that, in various embodiments, the features could be implemented using any other type of computing or processing architecture, such as special-purpose integrated circuits. Further, in some implementations, processor 316 may include a system of multiple processors and/or memory 318 may include a system of multiple computer-readable storage media. For example, in some implementations, system 300 may be implemented using a distributed computing environment in which multiple computing systems work in a distributed or coordinating fashion to implement various functions described herein. In some such implementations, system 300 may be a cloud computing system in which computing cloud-based resources perform the functions. In various implementations, the functions can be performed by servers, client devices, or a combination thereof.

Memory 318 may include data ingestion circuit 320, data preprocessing circuit 322, semantic extraction circuit 324, dynamic configuration circuit 326, model integration circuit 328, model enrichment circuit 330, and model analysis circuit 332. Data ingestion circuit 320 may be configured to receive data from various sources (e.g., building management system 102, external systems 350, user devices 360, etc.) and ingest the data into a digital representation of a space. For example, data ingestion circuit 320 may receive a csv file having a listing of building assets and may generate object entities for entity graph 170 based on each of the building assets. As another example, data ingestion circuit 320 may receive images of an interior of a space from user devices 360 (e.g., smartphones, etc.) and may embed the images into a 3D model of the space. In various embodiments, data ingestion circuit 320 converts various input formats. For example, data ingestion circuit 320 may convert from serialized BIM to Brick RDF (e.g., a JSON-LD) model, etc.), from Revit to Forge, from Revit BIM to SVF, from COBie to Brick RDF, from SCT to Brick RDF, from RAC to Brick, from Excel to Brick, from an old version of a file format to a new version of a file format, from Revit (e.g., IFC, etc.) to GeoJson, from Revit to TTL, and/or the like. In various embodiments, data ingestion circuit 320 may generate digital representations of buildings, floors, rooms, spaces, zones (e.g., HVAC zones, etc.), and/or the like based on received data. Additionally or alternatively, data ingestion circuit 320 may generate digital representations of relationships between entities (e.g., buildings, floors, etc.) such as spatial relationships (e.g., buildings [hasLocation] Floor [hasLocation] Room [hasLocation] Equipment, Zone (HVAC) [hasPart] Space, etc.). In various embodiments, data ingestion circuit 320 may store point values (e.g., sensor readings, measurements, etc.) based on received data. For example, data ingestion circuit 320 may receive an excel file including temperature readings associated with a space over a period of time and may integrate the temperature readings into a digital representation of the space such as entity graph 170.

Data preprocessing circuit 322 may perform various functions of received data to facilitate ingesting the data into a digital representation. For example, data preprocessing circuit 322 may perform semantic extraction (e.g., via semantic extraction circuit 324, etc.) on input strings to identify descriptive information within the strings (e.g., building identifiers, zone identifiers, equipment identifiers, times, dates, locations, etc.). As another example, data preprocessing circuit 322 may perform various dataset manipulations such as transposing a matrix (e.g., to facilitate simplified data ingestion, etc.) and/or processing data such as determining whether a location of “Madison” associated with a building refers to Madison, Wis. or Madison, Ala.

Semantic extraction circuit 324 may receive data and automatically (e.g., with little to no user intervention, etc.) extract semantic information from the data such as asset identifiers. For example, semantic extraction circuit 324 may receive a string and may analyze the string (e.g., parse the string) using machine learning (or artificial intelligence models such as a neural network, etc.) to extract one or more identifiers embedded within the string. For example, semantic extraction circuit 324 may receive the string “ZONE.AHU01.RM2008S.ZONE_AIR_TEMP” and may identify that the string relates to point data associated with an air temperature in a HVAC zone associated with room 2008S that is served by AHU01. As an additional example, semantic extraction circuit 324 may receive a string and may identify a space, a zone, a point type, and/or the like embedded in the string. In some embodiments, semantic extraction circuit 324 may extract classes and/or identifiers from strings. Semantic extraction from strings is discussed in detail in U.S. patent application Ser. No. 16/885,959 titled, “BUILDING SYSTEM WITH STRING MAPPING BASED ON A STATISTICAL MODEL” filed on May 28, 2020 and U.S. patent application Ser. No. 16/885,968 titled, “BUILDING SYSTEM WITH STRING MAPPING BASED ON A SEQUENCE TO SEQUENCE NEURAL NETWORK” filed on May 28, 2020, the entirety of both of which are incorporated by reference herein. In various embodiments, semantic extraction circuit 324 may extract semantic information from various sources. For example, semantic extraction circuit 324 may extract room names and/or dimensions from a SVG floorplan. In some embodiments, semantic extraction circuit 324 implements a hidden Markov Model (HMM). Additionally or alternatively, semantic extraction circuit 324 may implement a conditional random field (CRF) model. In various embodiments, semantic extraction circuit 324 generates recommendations for a user. For example, semantic extraction circuit 324 may generate semantic recommendations based on analyzing an input string. As another example, semantic extraction circuit 324 may receive the string “SDH_CHW2_CHP4_ALM” and may generate a recommendation that “SDH” is a building and “CHW” is either chilled water or cold water. In various embodiments, semantic extraction circuit 324 trains one or more models using training data. For example, semantic extraction circuit 324 may be trained on prelabeled strings (e.g., strings that a user has performed semantic extraction on, etc.). As an additional example, semantic extraction circuit 324 may be trained on entity names (e.g., point names, etc.). In various embodiments, semantic extraction circuit 324 augments one or more systems, such as OpenRefine (e.g., through one or more plugins or operators, etc.).

Dynamic configuration circuit 326 may modify operation of one or more devices and derive information therefrom. For example, dynamic configuration circuit 326 may turn on a fan associated with a known location within a building, may monitor one or more temperature sensors that have not been mapped to a location within the building, and may determine based on a change in temperature associated with one or more of the sensors that the one or more sensors are located in the location. In various embodiments, dynamic configuration circuit 326 is configured to fill gaps in a digital representation of a space. For example, a digital representation such as entity graph 170 may include a number of unlabeled/unassigned assets (e.g., smart lights not yet associated with a room, etc.) and dynamic configuration circuit 326 may derive the missing labels/assignments by operating various assets within a building (e.g., as described above, etc.). In various embodiments, dynamic configuration circuit 326 generates and/or modifies relationships within entity graph 170.

Model integration circuit 328 may integrate one or more models into a digital representation of a space. For example, model integration circuit 328 may receive a BIM associated with a building and may integrate information included in the BIM into a digital representation of the building (e.g., entity graph 170, etc.). In various embodiments, model integration circuit 328 extracts semantic information from data. For example, model integration circuit 328 may receive a simple vector format (SVF) file depicting a floorplan of a building and may extract dimensions of rooms in the floorplan from the SVF file and embed the dimensions in a digital representation of the building (e.g., entity graph 170, etc.). In various embodiments, model integration circuit 328 deduplicates between identifiers in various models. For example, a first model may include building data having an asset labeled with a first identifier and a second model may include building data having the asset labeled with a second identifier and model integration circuit 328 may determine that the first and second identifiers are associated with the same asset and may only generate a single instance of the first asset in a digital twin. In various embodiments, model integration circuit 328 uses machine learning and/or artificial intelligence to deduplicate between entities (e.g., asset identifiers, etc.).

In various embodiments, model integration circuit 328 may modify/enrich an existing model, such as a BIM, to become a digital twin of a building (e.g., use the BIM as entity graph 170 or change the BIM into entity graph 170, etc.). In various embodiments, model integration circuit 328 modifies existing models to include new information. For example, entity graph 170 may include more complete information than an imported BIM and model integration circuit 328 may modify the imported BIM to include the additional information included in entity graph 170. In various embodiments, model integration circuit 328 selects between versions of models. For example, model integration circuit 328 may prefer “central” BIM models if available but may also use “local” BIM models. In various embodiments, model integration circuit 328 resolves conflicts between various versions of models. For example, model integration circuit 328 may analyze two conflicting model versions to determine one or more aspects from each of the conflicting models that is most accurate and may ingest the one or more aspects.

In some embodiments, model integration circuit 328 augments one or more existing models. For example, model integration circuit 328 may link a COBie model with a graphical model using a unique identifier (e.g., a key, etc.). As another example, model integration circuit 328 may embed spatial metadata (e.g., floorplan dimensions, etc.) into a SVG floorplan. As yet another example, model integration circuit 328 may generate custom data within a model such as a BIM. For example, model integration circuit 328 may generate custom data (e.g., key/value pairs, etc.) and embed the custom data into a model such as a BIM to augment the model with more granular of data than would be natively possible. In various embodiments, model integration circuit 328 facilitates transferring augmentations between versions of models. For example, model integration circuit 328 may augment a first version of a BIM and may automatically augment (e.g., sync, etc.) a second version of the BIM when it is released. In various embodiments, model integration circuit 328 maintains a unique identifier for each model version. Additionally or alternatively, model integration circuit 328 may maintain unique identifiers for objects within a model. For example, model integration circuit 328 may generate a stable identifier for objects within a BIM model. As an additional example, model integration circuit 328 may generate global identifiers for objects within a model such as a BIM model and may automatically reapply the global identifiers to a subsequent version of the model. Global identifiers may facilitate performing operations across models (e.g., searching for an entity in entity graph 170 and/or a BIM model, etc.). In various embodiments, global identifiers are stored in a graph data structure (e.g., a digital twin of a space, entity graph 170, etc.). Therefore, a model such as a BIM model or a digital twin may display visual data such as a 3D model by retrieving a SVF model using the global identifier. In various embodiments, this solves existing problems associated with visualizing a space (e.g., in a web browser, etc.). In some embodiments, model integration circuit 328 facilitates serializing models. For example, model integration circuit 328 may serialize a BIM model.

Model enrichment circuit 330 may enrich an existing model using derived information. For example, model enrichment circuit 330 may enrich a digital representation of a building (e.g., entity graph 170, etc.) with information derived from the digital representation. In some embodiments, model enrichment circuit 330 generates a health metric associated with data. For example, model enrichment circuit 330 may operate an HVAC unit associated with a space, monitor the temperature in the space with a number of temperature sensors, and based on determining that one of the number of temperature sensors deviated from the rest of the number of temperature sensors may determine that either (i) the one temperature sensor is malfunctioning (e.g., needs to be repaired, etc.) or (ii) the one temperature sensor is not actually located in the space. To continue the previous example, based on the determination, model enrichment circuit 330 may modify point values (e.g., sensor readings, etc.) associated with the one temperature sensor to include a health metric that indicates that the “health” of the data (e.g., the validity, the trustworthiness, etc.) is in question. In various embodiments, systems (e.g., building management system 102, etc.) may use such health metrics during analysis and operation (e.g., discount sensor readings from sensors having health metrics that indicate their data may be untrustworthy, etc.). In various embodiments, model enrichment circuit 330 may derive information from existing data such as determining floorplan dimensions from a SVG floorplan.

In some embodiments, model enrichment circuit 330 enriches a digital representation of a space (e.g., a graph data structure, entity graph 170, etc.) with visualization data. For example, model enrichment circuit 330 may link 2D and/or 3D data to entities within a graph data structure to facilitate bidirectional control of data. For example, a user viewing a model of a building may select an element in the model to retrieve attribute information stored in a graph data structure representing the building. As another example, a user viewing a graph data structure of a building may select one of the entities in the graph data structure to retrieve a visual representation of the entity (e.g., a 3D model, etc.). As yet another example, a user viewing a 3D model of a building may wish to know which cameras have a view of a particular doorway and may select the doorway to retrieve information from a graph data structure storing a cameras and their associated views in order to retrieve links to camera feeds associated with cameras that have a view of the doorway.

Model analysis circuit 332 may analyze one or more models to generate information and/or actions. For example, model analysis circuit 332 may analyze a digital representation of a space to generate information such as predicted maintenance for assets within the space. In various embodiments, model analysis circuit 332 may analyze the relationships between points (e.g., data entities, etc.) to determine if behavior of one or more entities (e.g., a HVAC unit, etc.) is anomalous. For example, model analysis circuit 332 may perform pattern matching, performance modeling, and/or the like. In some embodiments, model analysis circuit 332 configures one or more other systems based on one or more models. For example, model analysis circuit 332 may generate fault detection and diagnostic (FDD) thresholds for a FDD system based on a digital twin of a space. In some embodiments, model analysis circuit 332 compares between models to generate information. For example, model analysis circuit 332 may compare a first digital twin associated with a first point in time to a second digital twin associated with a second point in time to identify changes and/or update configurations between models.

Entity graph database 312 may store one or more digital representations of spaces, people, and/or assets. In some embodiments, entity graph database 312 stores a digital representation of a building such as a digital twin. In various embodiments, entity graph database 312 includes one or more graph data structures such as entity graph 170. In various embodiments, smart configuration and commissioning system 300 updates entity graph database 312 to include information from building management system 102, cloud building management platform 140, external systems 350, user devices 360, deployed devices 370, and/or the like. In various embodiments, the one or more digital representations of spaces, people, and/or assets may represent the past and present states of the spaces, people, and/or assets and may be used to predict future states of the spaces, people, and/or assets. For example, each graph data structure (e.g., digital representation, etc.) may be serialized such that comparisons between versions of a digital twin may reveal how an entity associated with the digital twin changed over time. In some embodiments, changes in serialized versions of a graph data structure (or usage thereof) may trigger one or more actions. For example, if a new set of sensors is added to a data structure representing a room then smart configuration and commissioning system 300 may trigger a review of data associated with the room to determine things like if the room was split in two (e.g., during a renovation, etc.), and/or to determine whether a control scheme associated with the room needs to be updated. As an additional example, smart configuration and commissioning system 300 may determine that an occupancy sensor is no longer activated in a room and may trigger a review to determine if a change such as a sensor error or the room being converted into a storage closet are to blame. In some embodiments, actions are triggered across models. For example, if a new space is added to a security system then smart configuration and commissioning system 300 may review a lighting system to see if the change is reflected in the lighting system. As an additional example, if a space is added to a lighting controls system then smart configuration and commissioning system 300 may analyze an access control system to determine if the access policies for doors associated with the space can be inherited from the lighting controls system. In some embodiments, serialized digital twins are stored as a csv file, however one of skill in the art will appreciate that any suitable format may be used (e.g., RDF TTL, etc.). In various embodiments, data structures in entity graph database 312 represent parent/child relationships. Additionally or alternatively, entity graph database 312 may include information such as a space type, space dimensions, geocoordinates (e.g., associated with an entity such as a person or asset, etc.), a location of a nearest exit, locations of amenities (e.g., restrooms, kitchens, etc.), a link to a photograph of the space, a link to a floorplan file, and/or the like.

Entity graph database 312 may include one or more storage mediums. The storage mediums may include but are not limited to magnetic storage, optical storage, flash storage, and/or RAM. Entity graph database 312 may implement or facilitate various APIs to perform database functions (i.e., managing data stored in entity graph database 312). The APIs can be but are not limited to SQL, ODBC, JDBC, and/or any other data storage and manipulation API.

Storage 314 may store information associated with the operation of smart configuration and commissioning system 300. For example, storage 314 may store one or more machine learning models configured to analyze building data and generate predicted future states of operation. One of skill in the art will understand that storage 314 may suitable store many types of data and that, for the sake of brevity, all such types of data are not enumerated herein. Storage 314 may include one or more storage mediums. The storage mediums may include but are not limited to magnetic storage, optical storage, flash storage, and/or RAM. Storage 314 may implement or facilitate various APIs to perform database functions (i.e., managing data stored in storage 314). The APIs can be but are not limited to SQL, ODBC, JDBC, and/or any other data storage and manipulation API.

Referring now to FIG. 4, method 400 is shown for generating an entity graph, according to an exemplary embodiment. In various embodiments, smart configuration and commissioning system 300 performs method 400. For example, smart configuration and commissioning system 300 may receive information associated with a building being converted to use a building management system that utilizes a digital representation of the building and may generate a digital representation of the building (e.g., entity graph 170, etc.). At step 402, smart configuration and commissioning system 300 may receive space data. Space data may include data describing a layout of a space. In some embodiments, the space data includes hierarchies. For example, the space data may describe a building having floors which have rooms, etc. The space data may take many forms. For example, the space data may include a space graph (e.g., a graph data structure describing a space, etc.), a BIM, a floorplan, a list of spaces (e.g., for a custom dictionary, etc.), a user description, and/or the like. Additionally or alternatively, the space data may include data generated based on a scan of the building. For example, a building management system may perform a discovery operation (e.g., a scan, etc.) to discover connected devices within a building and may pass the discovered information to smart configuration and commissioning system 300. Additionally or alternatively, smart configuration and commissioning system 300 may receive other data (e.g., asset data, HR data, etc.). For example, in some embodiments, the space data may include a points list indicating data points associated with spaces.

At step 404, smart configuration and commissioning system 300 may generate object entities in an entity graph associated with spaces. Object entities associated with spaces can also be referred to as digital twins of the spaces, or space digital twins. For example, smart configuration and commissioning system 300 may generate object entities for each space included in the space data. For example, smart configuration and commissioning system 300 may generate a node corresponding to a building and a node corresponding to floor within the building and a node corresponding to a room within the floor. In various embodiments, smart configuration and commissioning system 300 may generate spatial relationships and/or classify spaces. For example, smart configuration and commissioning system 300 may generate an edge between a node representing a building and a node representing a floor within the building, wherein the edge represents a relationship between the building and the floor (e.g., building [hasFloor] floor, etc.).

At step 406, smart configuration and commissioning system 300 may generate object entities in an entity graph associated with assets. For example, smart configuration and commissioning system 300 may generate object entities for each asset included in a building. Object entities associated with assets may also be referred to as digital twins of the assets, or asset digital twins. For example, smart configuration and commissioning system 300 may generate a node corresponding to a HVAC system and a node corresponding to a fan within the HVAC system. In various embodiments, smart configuration and commissioning system 300 may generate asset relationships and/or classify assets (e.g., asset types, etc.). For example, smart configuration and commissioning system 300 may generate an edge between a node representing a HVAC system and a node representing a fan within the HVAC system, wherein the edge represents a relationship between the HVAC system and the fan (e.g., HVAC system [hasComponent] fan, etc.). Assets may include people, devices, furniture, lights, objects, supplies, equipment (e.g., HVAC equipment, etc.), decorations, and/or the like. Smart configuration and commissioning system 300 may receive asset information from an EAM system, a COBie file, a list of assets (e.g., for a custom dictionary, etc.), and/or the like. In some embodiments, the asset entities may be generated using data from a points list, such as data that may not necessarily be explicitly tied to an asset but may be indicative of the presence of an asset in a space. In various embodiments, smart configuration and commissioning system 300 may generate an asset graph (e.g., a graph data structure representing assets, etc.).

At step 408, smart configuration and commissioning system 300 may assign assets to spaces. For example, smart configuration and commissioning system 300 may generate relationships between object entities representing spaces and object entities representing assets. For example, smart configuration and commissioning system 300 may generate an edge between a node representing a HVAC system and a node representing a building, wherein the edge represents a relationship between the HVAC system and the building (e.g., HVAC system [servesSpace] building, etc.). In various embodiments, the relationships are bidirectional relationships. For example, an edge may represent a first relationships (e.g., FAN_1 [isControlledBy] CONTROLLER_2, etc.) and a second relationship (e.g., CONTROLLER_2 [Controls] FAN_1, etc.). In some implementations, the bidirectional relationships may not necessarily be direct counterparts or reciprocal relationships; for example, an edge between a thermostat entity and a room entity may indicate that the thermostat is in the room, and another edge may indicate that the room temperature is controlled by the thermostat. In some embodiments, smart configuration and commissioning system 300 assigns assets to spaces using relationships from received data (e.g., existing relationships, etc.). For example, smart configuration and commissioning system 300 may determine relationships between assets and spaces using information from an existing graph data structure (e.g., from a COBie file, from a EAM system, etc.), from a manual site survey, a list of assigned assets (e.g., for a custom dictionary, etc.), by processing strings to extract semantic information (e.g., as described above, etc.), via data manipulation (e.g., matching and/or clustering data, etc.), and/or the like.

At step 410, smart configuration and commissioning system 300 may assign data entities, or points, to assets. For example, smart configuration and commissioning system 300 may generate a data entity representing a point, or measurement value, and link (e.g., via an edge, etc.) the data entity to an asset (e.g., a node, etc.). In various embodiments, data entities include point values (e.g., sensor measurements, etc.). In various embodiments, smart configuration and commissioning system 300 may determine relationships between point values and assets. For example, smart configuration and commissioning system 300 may receive BMS configuration files and use the configuration files to link point values to assets (e.g., TEMP_SENSOR_1 has measurement “70_deg_F” at “14:20:02” on “10/2/2020,” etc.). Step 410 may include generating data entities (e.g., generating data entities from received sensor information, etc.). In some embodiments, smart configuration and commissioning system 300 assigns data entities to assets using relationships from received data (e.g., existing relationships, etc.). For example, smart configuration and commissioning system 300 may determine relationships between data entities and assets using information from an external point schedule, a site survey, by processing strings to extract semantic information (e.g., as described above, etc.), and/or the like. In various embodiments, step 410 includes assigning asset-less data entities to spaces. For example, smart configuration and commissioning system 300 may receive a list of sensor readings some of which are not associated with specific sensors and may assign the sensor readings that are not associated with specific sensors to a space (e.g., the space from which the sensors readings originated, etc.). In some embodiments, the points/measured values may be ingested into the entities for the assets/spaces themselves, as opposed to being represented as separate entities/nodes in the graph.

At step 412, smart configuration and commissioning system 300 may classify data entities. For example, smart configuration and commissioning system 300 may generate a relational object (e.g., an edge, etc.) between the data entity and a class entity. For example, smart configuration and commissioning system 300 may generate an edge representing that a sensor reading such as “70_deg_F” is of type TEMP. In some embodiments, smart configuration and commissioning system 300 classifies data entities using relationships from received data (e.g., existing classifications, etc.). For example, smart configuration and commissioning system 300 may classify data entities using information from built-in tags (e.g., of received data, etc.), a standard naming scheme, an existing schedule, “typical” naming (e.g., industry standards, etc.), historical databases (e.g., using an AI classifier, etc.), and/or the like. In some embodiments, step 412 is performed at least partially manually.

At step 414, smart configuration and commissioning system 300 may generate relational objects. For example, smart configuration and commissioning system 300 may generate edges in a graph data structure (e.g., entity graph 170, etc.) that represent relationships between nodes in the graph data structure. The relationships may include relationships between points (e.g., data entities, etc.), assets (e.g., object entities, etc.), and spaces (e.g., object entities, etc.). For example, the relationships may include an edge representing that a AHU serves a room (e.g., AHU_1 [servesSpace] ROOM_20S, etc.), an edge representing that a chiller feeds a bathroom (e.g., CHILLER_20 [Feeds] BATHROOM_20LL, etc.), an edge representing that an occupancy sensor measures the occupancy of a room (e.g., SENSOR_S98 [Measures] ROOM_22S, etc.). In some embodiments, smart configuration and commissioning system 300 relational objects from received data (e.g., existing relationships, etc.). For example, smart configuration and commissioning system 300 may generate relationships using information from built-in “slots” within tags (e.g., of received data, etc.), a standard naming scheme, an existing schedule, “typical” naming (e.g., industry standards, etc.), historical databases (e.g., using an AI classifier, etc.), and/or the like. In some embodiments, step 414 is performed at least partially manually. At step 416, smart configuration and commissioning system 300 may export an entity graph. For example, smart configuration and commissioning system 300 may export an entity graph constructed during method 400 for use by other systems (e.g., a BMS, etc.).

Referring now to FIG. 5, method 500 for classifying input strings is shown, according to an exemplary embodiment. In various embodiments, smart configuration and commissioning system 300 performs method 500. For example, smart configuration and commissioning system 300 may classify input strings using statistical analysis and/or machine learning as described above with reference to FIG. 3. In various embodiments, method 500 include the use of one or more APIs and/or SDKs to facilitate ingesting data from external sources. For example, a technician may use an API to ingest data and extract semantic information from an existing BMS into a digital representation associated with a newly installed system. In some embodiments, method 500 is performed automatically (e.g., with little to no user intervention, etc.). Additionally or alternatively, method 500 may be performed at least partially manually by a user (e.g., during a setup phase of a system installation, etc.). At step 502, smart configuration and commissioning system 300 may receive unclassified data. Unclassified data may include raw metadata, strings, and/or the like. For example, smart configuration and commissioning system 300 may receive strings from BMS configuration files (e.g., of a BMS system that is being upgraded, etc.) that are associated with a scan (e.g., a BACnet point scan, etc.) to discover connected devices within a building. In various embodiments, the unclassified data includes semantic information to be extracted.

At step 504, smart configuration and commissioning system 300 may identify semantic elements within the unclassified data. For example, step 504 may include parsing a string using a separator (e.g., separating “ZONE.AHU01.RM2008S.ZONE_AIR_TEMP” into “ZONE,” “AHU01,” “RM2008S,” “ZONE_AIR_TEMP,” etc.). In various embodiments, the semantic elements include object entities, data entities, and/or relationships between various entities. For example, smart configuration and commissioning system 300 may extract the relationship FLOOR_2 [hasLocation] BUILDING_1 from a string. In some embodiments, step 504 includes executing one or more machine learning models. For example, step 504 may include executing a LSTM model with character embedding to extract semantic information from strings. In some embodiments, step 504 includes surfacing proposed semantic elements (e.g., generated based on ML analysis, etc.) to a user for selection. In some embodiments, method 500 includes feeding a ML and/or AI model one or more examples of user-classifications (e.g., a string a user has manually classified, etc.) to train the ML and/or AI model and facilitate automated extraction of the rest of the strings.

At step 506, smart configuration and commissioning system 300 may segregate unclassified data based on the semantic elements. For example, smart configuration and commissioning system 300 may generate a multi-dimensional matrix having columns associated with the identified semantic elements from a 1-dimensional list of strings. In some embodiments, steps 504 and 506 repeat until a number (e.g., a threshold amount, etc.) of possible semantic elements have been extracted.

At step 508, smart configuration and commissioning system 300 may identify related elements within unclassified data. For example, smart configuration and commissioning system 300 may identify a number of sensors that are all of type TEMP_SENSOR. As another example, smart configuration and commissioning system 300 may identify a number of rooms that are on a specific floor of a building. In various embodiments, step 508 includes executing one or more machine learning models. For example, step 506 may include using a machine learning classifier to identify related elements within the data. Additionally or alternatively, one or more algorithms may be used to identify related elements. For example, an n-gram algorithm may be used to identify related elements.

At step 510, smart configuration and commissioning system 300 may cluster unclassified data based on related elements. For example, smart configuration and commissioning system 300 may cluster specific rows of a multi-dimensional matrix associated with elements that are related. In some embodiments, step 510 includes assigning one or more elements to a group. For example, a number of AHUs that serve a floor within a building may be tagged as serving the floor. In some embodiments, steps 1109 and 510 repeat until a number (e.g., a threshold amount, etc.) of possible related elements have been clustered.

At step 512, smart configuration and commissioning system 300 may label entities. For example, smart configuration and commissioning system 300 may label entities in a matrix as data entities, object entities, class entities, and/or the like. In various embodiments, smart configuration and commissioning system 300 may generate labeled entities (e.g., for an entity graph, etc.) based on the information surfaced in previous steps. For example, smart configuration and commissioning system 300 may label a row as being associated with a temperature sensor. In various embodiments, data in the matrix is grouped by entity. For example, entries in a first column of a matrix may be associated with unique entities (e.g., people, places, and/or assets, etc.).

At step 514, smart configuration and commissioning system 300 may transpose the matrix. In various embodiments, step 514 is optional. For example, step 514 may facilitate converting a matrix representing attributes associated with a number of entities into a matrix representing timeseries values generated by a number of entities. At step 516, smart configuration and commissioning system 300 may reconcile the matrix elements with an external system. In various embodiments, the external system is a server configured to receive data and perform one or more operations on the data. Additionally or alternatively, the external server may be part of smart configuration and commissioning system 300. For example, step 516 may include sending location information associated with one or more entities to a server to determine whether the location information is associated with a first location or a second location (e.g., whether “Madison” refers to Madison, Wis. or Madison, Ala., etc.). In various embodiments, reconciling the matrix may include computing one or more functions using the matrix information. For example, smart configuration and commissioning system 300 may enrich the matrix information by reconciling the matrix to derive distance measurements associated with the distance between each entity within the matrix (e.g., the distance between a first building and a second building, etc.). At step 518, smart configuration and commissioning system 300 may export the matrix. In various embodiments, the matrix may be used by other systems to determine information and/or actions. For example, data ingestion circuit 320 may use the matrix to generate a digital representation of a space and/or model integration circuit 328 may use the matrix to integrate existing data (e.g., extracted from unclassified strings provided by a legacy BMS, etc.) into a digital representation.

Referring now to FIGS. 6A-B, diagram 600 illustrating input string manipulation is shown, according to an exemplary embodiment. In various embodiments, smart configuration and commissioning system 300 implements input string manipulation as shown in diagram 600. In various embodiments, diagram 600 illustrates input string manipulation as described in detail above with reference to FIG. 5. Diagram 600 starts with input list 610. Input list 610 may include a number of unclassified strings. For example, input list 610 may include a number of strings from a BMS configuration file. As another example, input list 610 may include a number of strings from a BACnet point scan (e.g., a BMS discovery scan, etc.). Input list 610 may include one or more input strings 612. Input strings 612 may be associated with an entity (e.g., people, places, and/or assets, etc.) within a space such as a building. Additionally or alternatively, input strings 612 may be associated with data (e.g., a data entity, a point value, etc.). In various embodiments, input strings 612 include semantic information (e.g., information describing a space and/or entities within a space, etc.).

At step 602, smart configuration and commissioning system 300 may segregate input list 610 based on semantic elements to generate matrix 620. For example, smart configuration and commissioning system 300 may generate one or more columns based on input list 610. Matrix 620 may include elements 622-628. One of skill in the art will appreciate that matrix 620 may include any number of elements (e.g., five elements, a thousand elements, etc.). Each of elements 622-628 may be associated with different information. For example, a first element 622 may be associated with a space type (e.g., ZONE, etc.), a second element 624 may be associated with a device identifier (e.g., AH1N, etc.), a third element 626 may be associated with a room identifier (e.g., RM159, etc.), and a fourth element 628 may be associated with a data type (e.g., Day/Night, etc.).

At step 604, smart configuration and commissioning system 300 may cluster data based on related elements. For example, smart configuration and commissioning system 300 may cluster matrix 620 based on similar values (e.g., “heat cool” vs. “heat coool,” etc.). In various embodiments, step 604 may facilitate correcting errors (e.g., user input errors, etc.). In some embodiments, step 604 includes performing one or more matrix operations on matrix 620. For example, smart configuration and commissioning system 300 may transpose matrix 620 to generate transposed matrix 630. Transposed matrix 630 may include a number of parameters 634-644 associated with a specific entity (e.g., entity 632, “ZONE:AH1N:RM157,” etc.). Parameters 634-644 may include one or more variable values and/or pointers to one or more variable values. For example, parameters 634-644 may include a zone air temperature (e.g., Zone Air Temp_1397, etc.), a day/night parameter (e.g., Day Night_5874, etc.), a heat/cool parameter (e.g., Heat Cool_7354, etc.), an auxiliary temperature (e.g., AUX TEMP_1009, etc.), a control setpoint (e.g., CTL STPT_4703, etc.), a valve command (e.g., VLV 1 COMD_4223, etc.), and/or the like. In various embodiments, transposed matrix 630 may be used by smart configuration and commissioning system 300 to setup and/or modify a digital representation of a space such as a graph data structure.

Referring now to FIG. 7, system 700 for auto-commissioning of a space, shown as room 702, is shown, according to an exemplary embodiment. In various embodiments, smart configuration and commissioning system 300 auto-commissions room 702. For example, smart configuration and commissioning system 300 may analyze a graph data structure representing room 702, identify information in the graph data structure that needs completing/updating, and perform one or more operations to derive information to at least partially complete and/or update the graph data structure. As a general example, smart configuration and commissioning system 300 may receive an entity graph (e.g., entity graph 170, etc.) with a number of unlabeled sensors (e.g., sensors not associated with a specific space, etc.) and may operate one or more HVAC systems within a building while measuring operation of the number of unlabeled sensors to determine a location within the building that each of the number of unlabeled sensors is associated with. Room 702 is shown to include thermostat 704 and temperature sensor 706. In some embodiments, room 702 includes one or more users. In some embodiments, the one or more users having devices (e.g., mobile devices, etc.) that may be used to provide feedback to smart configuration and commissioning system 300.

At step 710, smart configuration and commissioning system 300 may modify an operation of room 702 and/or one or more entities (e.g., building assets, etc.) associated with room 702. For example, smart configuration and commissioning system 300 may modify operation of an HVAC system serving room 702, may modify operation of one or more smart lights located in room 702, and/or the like. In various embodiments, step 710 modifies one or more environmental parameters associated with room 702. For example, step 710 may modify a temperature of room 702, a lighting in room 702, a sound level in room 702, an asset within room 702 (e.g., turning on/off a television, etc.), and/or the like.

At step 720, smart configuration and commissioning system 300 may measure an effect of step 710. Additionally or alternatively, smart configuration and commissioning system 300 may receive measurements from another system (e.g., building management system 102, etc.). Step 720 may include receiving sensor information from one or more sensors. For example, step 720 may include receiving a temperature measurement from at least one of thermostat 704 and/or temperature sensor 706.

At step 730, smart configuration and commissioning system 300 may modify a graph data structure such as entity graph 170. For example, smart configuration and commissioning system 300 may modify entity graph 170 to generate an edge connecting a node representing thermostat 704 to a node representing room 702, wherein the edge represents that thermostat 704 is located within room 702. In various embodiments, step 730 includes analyzing received data to determine relationships between various entities. For example, smart configuration and commissioning system 300 may determine that thermostat 704 is located in room 702 because thermostat 704 measured a temperature increase corresponding to what would be expected based on operation of a HVAC system during step 710. In some embodiments, step 730 includes generating data to fill in gaps in an existing graph data structure (e.g., a digital representation of room 702, etc.). For example, smart configuration and commissioning system 300 may generate relationship data describing a location of a sensor for an existing sensor that is missing a location. In various embodiments, step 730 includes analyzing data from various sources. For example, step 730 may include analyzing user feedback from one or more users located in a room. For example, smart configuration and commissioning system 300 may operate a HVAC system that is not linked to which rooms it serves and may receive user feedback indicating that a specific room suddenly changed temperature (or became uncomfortable, etc.) and may determine that the HVAC system serves the specific room. As another example, smart configuration and commissioning system 300 may turn on/off a television that has not been associated with a specific space in a digital representation of a building and may receive user feedback that a television in a specific room turned on/off and may determine that the television is located in the specific room. In various embodiments, step 730 includes generating one or more nodes and/or one or more edges.

Additionally or alternatively, step 730 may include generating one or more health metrics. For example, smart configuration and commissioning system 300 may generate a health metric associated with thermostat 704 that indicates that data from thermostat 704 may not be valid. As a brief example, smart configuration and commissioning system 300 may determine that thermostat 704 is supposedly located in room 702, however upon changing a temperature of room 702, smart configuration and commissioning system 300 may only observe a change in temperature measurements from temperature sensor 706 (e.g., and/or one or more other temperature sensors, etc.) and may determine that thermostat 704 may be malfunctioning (e.g., not producing reliable data) and may generate a health metric associated with thermostat 704. Additionally or alternatively, smart configuration and commissioning system 300 may determine that thermostat 704 is in fact not located in room 702 (e.g., which would explain why thermostat 704 did not register a change in temperature, etc.). In various embodiments, health metrics may be used to reduce nuisance alarms and/or prevent alarm fatigue. For example, building management system 102 may suppress alarms associated with data having a health metric that indicates that the data may be unreliable.

Referring now to FIG. 8, system 800 for digesting information into an entity graph is shown, according to an exemplary embodiment. In various embodiments, smart configuration and commissioning system 300 digests information into a graph data structure such as entity graph 170. In various embodiments, smart configuration and commissioning system 300 may generate a digital representation of a space based on ingested data. System 800 is shown to include entity graph database 312. In various embodiments, entity graph database 312 includes one or more graph data structures. Smart configuration and commissioning system 300 may receive data from one or more sources and integrate the received data into one or more graph data structures of entity graph database 312. In various embodiments, by combining a number of data sources smart configuration and commissioning system 300 may generate a more complete and detailed representation of an entity. In various embodiments, digesting information into an entity graph may include eliminating duplicates between and/or within datasets. For example, a first HR database may include a first individual and a second visitor registration system may include the first individual and smart configuration and commissioning system 300 may deduplicate the first individual to create a single data representation for the first individual.

In various embodiments, sources 802-832 are integrated (e.g., by smart configuration and commissioning system 300, data ingestion circuit 320, data preprocessing circuit 322, semantic extraction circuit 324, model integration circuit 328, etc.) into entity graph database 312. For example, smart configuration and commissioning system 300 may integrate information from BIM 802 (e.g., IFC files, Revit files, RDF graph models, TTL data, etc.), building floorplan 804 (e.g., SVG images, etc.), HR database 806, email directory 808, ACS 810, EAM system 812 (e.g., COBie files, excel documents, csv files, etc.), facility management systems/software 814, security system 816, indoor maps 818, system scan 820 (e.g., a BACnet scan, etc.), BMS 822, DHCP server logs 824, lighting control system 826, visitor registration system 828, parking management system 830, user device 832, and/or the like.

Referring now to FIG. 9, method 900 of augmenting an entity graph with additional information is shown, according to an exemplary embodiment. In various embodiments, smart configuration and commissioning system 300 performs method 900. For example, smart configuration and commissioning system 300 may perform method 900 to generate additional information for a graph data structure that may facilitate operation of a space such as a building. In various embodiments, the additional information includes a health metric. The health metric may be associated with an accuracy of data. For example, a health metric associated with a relationship between two entities may indicate the likelihood that the relationship is true. As another example, a health metric associated with a sensor reading may indicate the likelihood that the sensor reading is accurate (e.g., describes a true value associated with a measured parameter, etc.).

At step 910, smart configuration and commissioning system 300 may identify one or more entities within an entity graph. For example, smart configuration and commissioning system 300 may identify a node within a graph data structure corresponding to an asset within a building. At step 920, smart configuration and commissioning system 300 may operate the identified entity 920. Additionally or alternatively, step 920 may include operating one or more entities associated with the identified entity. For example, the identified entity may include a room and step 920 may include operating a HVAC system that serves the room (or is thought to serve the room, etc.).

At step 930, smart configuration and commissioning system 300 may compare an effect of operating the entity to an expected effect. For example, smart configuration and commissioning system 300 may expect that operating a HVAC system associated with the room would result in measuring an increased temperature in the room, however smart configuration and commissioning system 300 may observe that no such change occurs. In various embodiments, step 930 includes receiving measurements from one or more entities (e.g., assets, devices, users, etc.). For example, smart configuration and commissioning system 300 may measure the effect of operating an entity (e.g., step 920, etc.).

At step 940, smart configuration and commissioning system 300 may generate a health metric associated with the entity based on the comparison. For example, smart configuration and commissioning system 300 may generate a metric that describes the reliability of sensor data. As another example, smart configuration and commissioning system 300 may generate a metric that describes the likelihood that an edge representing a relationship between two nodes is accurate. In various embodiments, smart configuration and commissioning system 300 may generate a health metric associated with a high degree of accuracy/confidence based on observing an effect of operating the entity consistent with an expected effect. Similarly, smart configuration and commissioning system 300 may generate a health metric associated with a low degree of accuracy/confidence based on observing an effect of operating the entity that deviates (e.g., by some threshold, etc.) from an expected effect. For example, a room may include a number of temperature sensors and in response to operating an HVAC system serving the room all of the number of temperature sensors in the room except for one may indicate a change in temperature. To continue the example, smart configuration and commissioning system 300 may determine that the one temperature sensor is faulty (e.g., producing unreliable temperature readings, etc.) and/or the one temperature sensor is not actually located in the room (e.g., a digital representation of the temperature sensor has been incorrectly mapped to the room, etc.). Based on the determination, smart configuration and commissioning system 300 may perform one or more actions such as saving a health metric associated with point values of the temperature sensor (e.g., the health metric indicating that the point values have a low degree of reliability, etc.), ordering maintenance on the temperature sensor, updating a graph data structure to correctly map the temperature sensor with a new space, and/or the like. At step 950, smart configuration and commission system 300 may store the health metric in the entity graph. For example, smart configuration and commissioning system 300 may generate a new data structure (e.g., a data entity, a node, etc.) associated with point values of the temperature sensor.
